Yes I didn't think I expressed that clearly.

I make a distinction between constructive feedback and criticism.

The difference in my mind is that criticism is the habit of actively looking for the negative (i.e. begin negative for the sake of it or to attempt to bring someone down), while constructive feedback (or what you might call 'constructive criticism') is suggesting improvements (which is positive).

What causes a comment to fall into one category or the other depends on whether the person attempts to put forward a solution.
Only pointing out "I don't like this or that" isn't useful information to me while
"I'm not able to listen to the whole show on my commute, can you reduce the episode length?" is.

That might come off as being nit picking but it's my ability to be specific about meaning that people say is what makes me a clear communicator :)

So when I asked for encouragement, that is what I wanted on this occasion. Other times when I want the more critical eye, I will ask for it.

I don't want an echo chamber put it that way :)
I appreciate you challenging me on what I said.
